ORE-CONCENTRATOR.

Patented Nov. 11, 1919.

Application filed January 24, 1917. Serial No. 144,151.

To all whom it may concern:

Be it known that I, VVILLIAM F. WALDA, a citizen of the United States of America, and resident of Fort Wayne, in the county of Allen and State of Indiana, have invented certain new and useful Improvements in (he-Concentrators, of which the following is a specification. a This invention relates to improvements inore concentrators of the reciprocating table type, and pertains particularly to construction for supporting the table proper in The obj ect of the improvement is to so support the deck that it may be moved freely in its reciprocal action while being supported and at the same time be free from influences that tend to augment inherent detrimental vibrations that sometimes develop when the deck is reciprocated rapidly. Another object is to provide means for maintaining, constantly,-lubrication of the supporting bearings.

The above objects are accomplished by the construction illustrated in the accompanying drawings, in which Figure 1 is a perspective view of the under construction of a concentrator showing the bearing pockets in connection therewith;

Fig; 2 is a plan view of the underside of the reciprocating deck and showing also the arrangement of feet that are secured thereto;

Fig. 3 is a transverse sectional view of the concentrator at a point adjacent the head end thereof;

Fig. 4 is a side elevation of the machine shown partly in longitudinal section;

Fig. 5 is a vertical section of one of the bearing pockets and the corresponding foot in bearing relation therewith;

.Fig. 6 is a bottom plan view of the feet; and

Fig. 7 is a plan view of one of the bearing pockets.

Similar characters of reference indicate corresponding partsthroughout the Various views and referring now to the same:

The illustrations show the adaptation of the present invention to a concentrator of known construction and which is disclosed in Letters Patent of the United States No. 1,026,764 issued to Gustave A.- Overstrom on May 21, 1912, which construction is herein presented as an example to disclose the use of the invention. The invention however, may

to the opposite one.

one of 1 be readily adapted to concentrators and other machinery differing from that herein shown. In the present instance the tilting frame (1) of the machine has arranged thereon responding pipes (4), the ends of the pipe entering the boxes at a point above the level ,of the bearing surfaces of the blocks therein, the purpose of the pipes being to convey the liquid lubricant from one pocket Also, one of each pair of pockets has a feed-pipe (5) connected therewith through which lubricant is re ceived. Secured to the under side of the reciprocating deck (6) are numerous castings having pendant feet (8), that are positioned to rest respectively upon the blocks (3) correspondingly. In the'face of each foot are made oil-grooves (9) to facilitate movement of lubricant to the contacting surfaces of the foot and block. The castings (7 are supported in their connection with the deck by laterally arranged angle irons (1 0) which serve to hold the castings fixedly in position.

The contacting surfaces of the feet and bearing blocks are approximately of equal area, and the weight of the reciprocating deck is borne by the bearing blocks with the feet resting thereupon, the bearing surfaces of the blocks and feet being smooth and submerged in the lubricant (11) that is sup plied to the pockets admit of the movement of'the deck in any direction parallel to the plane of the bearing surfaces.

The'deck (6) is also provided with pullbearings (12) and (13) respectively at its opposite ends which are actedupon oppositely by the spring-puller (14) at the one end and the driving-head (15) at the other. The action of the springp-uller and drivinghead effects the reciprocation of the deck and holds the latter in longitudinal tension and also in alinement upon its bearings which consist of the feet and bearing blocks.

As the table is reciprocated upon its bearings in the direction applied thereto by the diving-head ad spring-puller, the feet slide bearing surfaces so as to admit of free movement of the deck upon itsi bearingsas-it is driven and also asitmay vibrate more or less laterally; Such inherent lateral trembling movements of the deck as may occur areunrestricted by'the supporting bearings icomposedfo f the blocks and feet, as their contacting surfaces admit of free movement f the deck in'all directions in a plane paral- "lelto; thatof the contacting surfaces. Thus, :re-actionary. vibrations of the deck, such as jve'rtic'al trembling, do notdevelop and the r I Y efficacyoffthe concentrating action of the machine is thereby enhanced inasmuch as j vertical trembling. of the deck, dis turbs settlement of. mineral values] thereon.

' The method'of applyingreciprocal movement'to the d'eckby means of the. springpuller at] one end thereof and-the drlvinghead at theopposite end, contributes to the smoothness and directness of action of the deck upon the bearings. The draft of the puller and'driving-head being opposite, the deck is held in tension anddirectly i n'aline meat with the intended direction of re'ci rocal movement, and the freedom of the eck f to be moved byithe' actuating mechanism afforded by its supporting bearings, obviates re-actionary vibrations that cause detrimental disturbances of the mineral values during transit on the surface of the deck.

What I claim is 1. In bearings forsuppirtin "reciprocable.

concentrating'tables and the li e, 'a series of pendantifeet rigidlyattached to the table, and each having a'flat bearing face at its bottom; and a corresponding series of pockets suitably mounted, and each having'an upwardly projecting block therein with a flat upper face extending in a plane beneath I "the to'p 'of'the pocket and adapted to. admit of movement of the corresponding foot bear- I I Gcptes of this patent may be obtained'for- ,ing'thereon' in any direction parallel with V V the face thereof.

2. In bearings for supporting reciprocable concentrating tables and the like, a multi: pilicity of pendant feet rigidly attachedto the table; a corresponding series of pockets suitably mounted, each having therein an elevated flat bearing face extending in a plane beneath the top of the pocket and adapted to afford bearing support for the corresponding foot and admit of slidin movements thereofin all directions paralle with the face thereof, eachpocket being ada ted to contain lubricant to a level above the 'earing face therein; and means for conveying lubricant to said pockets."

3.111 bearings for supporting reciprocable concentrating tables and the like, a multiplicity of suitably mounted pockets, each having therein an upwardly projecting block with a flat upper face, there being a space within the pocket extending entirely around the blocktherein, said flat face lying in a plane lower than the top of the pocket;

and a corresponding multiplicity of pendant feet rigidly fixed. to the table and respectively projecting into the pockets and resting upon the blocks therein correspondingly. 4. A bearing for sup orting a reciprocable "membena casting wih a box-like pocket suitablymounted andhaving a central upwardlyprojecting block therein with a flat upper face, there being a space within the pocket extending entirely around the block, said pocket beingadapted to hold'lubricant to a level above said face; and a casting fixed to the reciprocable member having a flange extending downwardly over the top of thepocket upon the exterior thereof, and a central pendant foot having a fiat face at its bottom adapted to rest upon the corresp'ondin bearing face of the block, said castings eing so formed as to admit reciproeating movements of the foot upon the block in all directions parallel with said faces.

Intestimony whereof I afiix my signature, in presence of two witnesses.
